Trichocentrum longicalcaratum

I've shown other clones before, but this was a nice blooming of another clone.

 

I was using an older camera body for a few months earlier this year. I don't have another clone open right now to compare, but this one does seem especially bright.

 

It is frequently labeled as T. brandtiae so there may be some info under that name. Charlie Baker doesn't have a culture sheet on the orchid culture website, but does cover it in the Oncidium book. It is a slow grower and the buds take forever to develop.

I grow it usually w/ 56F minimum and 80F maximum, but have also grown at 50-52F minimum. It may actually prefer warmer conditions, but I don't have them. Dilute fertilizer at every watering, moderate light, good humidity and a boyant atmosphere, almost daily watering most of the year but little or no moss at the base so that it dries quickly.

 

That can be arranged! I think keeping them too wet is a problem. In my experience, they do best when allowed to dry fast and be watered frequently.

 

It might be a bit overblown to say "Sorry for your loss," but I'll say it anyway. Personally, I have never done well with tigrinum.

I like your current avatar (Eria pannea) very much.
